Security Bulletin
Summary
These vulnerabilities in the WebSphere eXtreme Scale monitoring console may
allow an attacker to gain access to the monitoring console, getting read/only
access to statistics data on grid usage.
Vulnerability Details
CVEID: CVE-2015-2025
DESCRIPTION: IBM WebSphere Extreme Scale could allow a remote attacker to
obtain sensitive information, caused by the failure to set the secure flag for
the session cookie in SSL mode. By intercepting its transmission within an
HTTP session, an attacker could exploit this vulnerability to capture the
cookie and obtain sensitive information.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104053 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:P/I:N/A:N)
CVEID:CVE-2015-2026
DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to cross-site request
forgery, caused by improper validation of user-supplied input. By persuading
an authenticated user to visit a malicious Web site, a remote attacker could
send a malformed HTTP. An attacker could exploit this vulnerability to perform
cross-site scripting attacks, Web cache poisoning, and other malicious
activities.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104054 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-2027
DESCRIPTION: IBM WebSphere Extreme Scale could allow a local user to bypass
security on another user's session due to it improperly logging out the
previous user.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104056 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-2028
DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to a HTTP response
splitting attack. A remote unauthenticated attacker could specify a specially
crafted URL to inject a malicious response to future requests.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104057 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-2029
DESCRIPTION: IBM WebSphere Extreme Scale could allow a remote attacker to
hijack a user's session, caused by the failure to invalidate an existing
session identifier. An attacker could exploit this vulnerability to gain
access to another user's session.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104058 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-2030
DESCRIPTION: IBM WebSphere Extreme Scale uses an inadequate account lockout
setting that could allow a remote attacker to brute force account credentials.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104070 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
CVEID: CVE-2015-2031
DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to cross-site
scripting, caused by improper validation of user-supplied input. A remote
attacker could exploit this vulnerability using a specially crafted URL to
execute script in a victim's Web browser within the security context of the
hosting Web site, once the URL is clicked. An attacker could use this
vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base Score: 3.5
